The Benefits of Zero Gravity – Like the zero gravity astronauts experience in space, the SmartChair provides a weightless experience to relieve tension, stress and muscle discomfort. With two zero gravity positions the experience promotes overall well-being, reducing your heart rate, lowering blood pressure, soothing stress, and calming both the body and mind for a one of a kind relaxation experience. The steady rhythmic massage soothes fatigued muscles, releases tension and restores a normal, steady heart rate by assisting in the transmission of oxygen-rich blood throughout your entire body. Select to achieve weightless-type posture. Press again for a deeper recline, and again to turn off.
